Oil and gas spill report for April 21

The following spills were reported to the Colorado Oil and Gas Conservation Commission in the past two weeks.

Information is based on Form 19, which operators must fill out detailing the leakage/spill events. Any spill release which may impact waters of the state must be reported as soon as practical. Any spill of five barrels or more must be reported within 24 hours, and any spill of one barrel or more which occurs outside secondary containment, such as metal or earthen berms, must also be reported within 24 hours, according to COGCC rules. Spills and leaks are typically found during routine maintenance on existing wells, though some actual “spills” do occur among the 19,000-plus wells in the county.

Bayswater Exploration & Production, reported that on April 2, equipment failed at a tank battery in Windsor. A water leg was lost in a separator and about 23 barrels of oil were spilled. The spill was contained within the berm and about 13 barrels of oil were recovered with a vacuum truck. The company re-leveled the separator to remove slight slope towards the water box end.

Noble Energy Inc., reported that on April 7, a water vault was found leaking at a well in LaSalle. The company shut in all equipment and began remediation. It is unknown how much oil and water were spilled and none were recovered. The company will continue to check water vaults to determine leaks and replace the vaults.

Noble Energy Inc., reported that on April 9, it was determined that flow lines near LaSalle, Kersey and Keenesburg had developed leaks. The crews shut in all equipment and began remediation. It is unknown how much oil and water were spilled in the three areas and none were recovered. The company will continue to check flow lines to determine leaks.

Bonanza Creek Energy Operating Company LLC, reported that on April 11, the crew was relocating two concrete water vaults when they noticed a historical produced water release at a tank battery in Kersey. The release occurred inside secondary containment. The amount of water spilled is to be determined and none has been recovered. The crew removed the water vaults and will excavate the impacted soil to take to a disposal facility. The company will continue to monitor and inspect water vaults.
